What is a US size 9 in EU?
US men's 9 equals EU 42 on the Paris-point formula (foot length ≈ 27 cm × 1.5, rounded). EU always rounds to whole sizes — treat it as the closest match, not an exact half-size.
Is US shoe size the same as EU?
No. US uses barleycorn length with a −22 offset; EU uses foot length in cm × 1.5. The same foot is labelled differently — always convert through foot length in millimetres.
